Number of pages: 106
College students who wish to know something of the hyperbolic trigonometry on account of its important and historic relations to each of those branches, will find these relations presented in a simple and comprehensive way in the first half of the work. Readers who have some interest in imaginaries are then introduced to the more general trigonometry of the complex plane, where the circular and hyperbolic functions merge into one class of transcendents, the singly periodic functions, having either a real or a pure imaginary period.
